It's a thermostatic snap switch and a small, low-drain, fan with a 12-volt brush-type motor, to be mounted in the back of the fridge space and help the airflow past the coils. Not sure what the setpoint is but I suspect it's about right to cool your diodes. Intended for coming on when the day is hot enough that convection cooling with a 4-foot chimney is inadequate.
Don't know how long the motor will last. (Mine outlasted the cooling coils, which failed a couple weeks ago and gave me a couple lungfulls of ammonia before I made it out the door. B-( Probably had at least a years worth of run time so far.) But if the motor goes out (or if you don't like it) you can always use the snap switch with something you trust better. Or use two of 'em for redundancy.
I can't remember ever seeing a travel trailer (or mobile home) on this island. I'll have to keep my eyes open for one. There probably isn't much market for them on an island the size of a postage stamp.
Anyway, I've found a snap switch now (see above), so I'm a happy camper.
